All this is according to a new study of 6,600 consumers conducted by Market Force Information, customer intelligence solutions. Market Force’s study was designed to uncover where consumers prefer to shop, as well why. Qualities such as Shoppers scored Trader Joe’s above all others. Publix, Whole Foods, Wegmans and ALDI also ranked high on the customer delight index,

When asked to rate their satisfaction with their most recent grocery store experience and their likelihood to refer that grocer, consumers scored Trader Joe’s above all others. Publix, Whole Foods, Wegmans and ALDI also ranked high on the customer delight index, which reveals the intersection between overall satisfaction and the likelihood of recommending a grocer to friends and family.

Interestingly, shoppers ranked a convenient location as the most important reason for store selection, even more important than low prices. Sales, merchandise variety, strong store brands and one-stop shopping rounded out the top five most important store attributes.

Way down at the bottom at the bottom of important attributes were green concerns. Having a sustainable environment and green policies ranked last with just 6 percent of respondents ranking these attributes as important.

There are lots of regional preferences as shoppers show a good degree of loyalty to local favorites such as Publix in the South and Meijer in the Midwest. Supermarket giant scored high in most markets save the Northeast and Loblaw's reigned supreme in Canada.

But what inspires such loyalty? Market Force notes that convenience is key but a number of other factors combine to lend a store favored status including fast checkout, friendly associates and atmosphere are important points of differentiation.

When it comes to grocery store preferences, size doesn't seem to matter. That Trader Joe’s, with just 400 stores, ranks No.1 with shoppers proves that smaller can be better. Discount chains and Walmart ranked high in one-stop shopping but little else when it came to shopper's preferred stores.

Supermarkets inspire pretty dramatic opinions. Shoppers love or hate them, with a fiery passion. Whether it's convenience, low prices or customer service, shoppers go out of their way to frequent their stores of choice. Have a favorite? You aren't alone.
